The situation: A supplier and a business buyer signed a supply contract setting quantity, price and a payment date. The supplier delivered the goods and issued the invoice, but the buyer delayed and then refused to pay, raising vague objections about quality or timing without clear evidence.
Applicable law: The dispute falls under the contract rules of the Chinese Civil Code, where each party is bound by what was agreed. A written contract plus delivery/acceptance proof and invoices strengthen the creditor's position in claiming the amount due and any agreed late-payment compensation.
Typical outcome: When the paperwork is in order, the buyer is usually required to pay, whether through an early amicable settlement or a formal claim. Weak documentation, by contrast, prolongs the dispute and lowers the chance of full recovery.

🎓 The lesson / takeaway
Lesson: Always rely on a written contract with clear payment terms. Keep delivery/acceptance proof and invoices, and act early at the first delay instead of waiting, because each extra day makes the debt harder to recover.
